Parameters : r4 = Target Reaction Ability ID (determined from Target reaction set)

If Used Ability do not cost MP ( 0x801938eb ) - skip routine (no reaction)
Test Unit Brave% as chance to react : skip the routine if failed

If Targeted Unit react :
- Store Reaction Ability ID in Target Data 0x19e (= current action 0x0e)
- Store Used Ability MP (from 0x801938eb) in Target data 0x1b2 (current action 0x26) - last attack received ?
